Following his recent hospitalisation for exhaustion and sleep deprivation, the newly blonde 'Famous' rapper, 39, strolled into Trump Tower in New York City today to meet with US President-Elect Donald Trump.

The pair went on to pose for photographs in the lobby, with Donald, 70, telling reporters Kanye is "a good man. We've been friends for a long time". He added that they had been talking about "life", and gave him a warm hug.

As Kanye sent social media into a tizzy, with fans calling him everything from "a sell-out" to "crazy", one big question remained...why was he there in the first place?

According to E! News, Kanye met with Donald to discuss becoming an "ambassador of sorts", with a source also telling the outlet that the president-elect is interested in getting the hip-hop star involved in an "entrepreneurial leadership role".

The newbie politician's team reportedly reached out to Kanye for the meeting. Another source added that "Trump thinks [Kanye is] a great role model when it comes to business".

Their meeting comes weeks after Kanye shocked fans after Donald was declared the winner of the presidential election by telling the audience at one of his concerts that if he had voted, he "would've voted for Trump".

Not long after that, Kanye cancelled the rest of his Saint Pablo Tour, and was hospitalised in late November for sleep deprivation and exhaustion.

He was also diagnosed with temporary psychosis, and was released after spending over a week at UCLA Medical Center.

Kanye re-emerged for the first time since his breakdown at a Los Angeles art installation last week.

At the 2015 MTV Video Music Awards, Kanye declared that he'll run for President in 2020. When Trump won the presidency, thousands took to social media to ask Kanye to dethrone Trump.

We wonder how they feel about the possibility of a President Kanye now.
